tennis balls

I parked in a Wal-Mart parking lot and was walking to the front door when I noticed two tennis balls. They looked new, a bright green. I picked them up and stuck in my left front pocket thinking I would give them to my friend who is a tennis playing nut. Just after i got in the store, I saw a lady who goes to our church. One of those people that loves to talk and talk. As she was talking to me, I noticed she kept looking down at my left leg. Finally, she ask "what do you have?" I said, "Oh, tennis balls". Then she said "Oh my, that must hurt, I have had tenis elbow and it hurt something awful. I FORGOT WHAT I WAS THERE FOR.
